years old and i bike about... on the average, abouten miles a day. ndays, i have a son-in-law... we have a son-in-law who is... he's only 40 years old, and he's got a lot more energy than i have. and so, on sundays, we go up to mt. rubideaux, but of course, he's way, way ahead of me. mirich: their body adjusts to that higher activity level, cardiovascular fitness, strength, flexibility, and then they'll find that, "boy, i have more energy. i am less stiff when i need to go out and mow the lawn or go shopping or to visit the grandkids. i'm sleeping better. i'm requiring less blood pressure medications. my diabetes is better controlled. i'm now able to get off my insulin and go on to an oral pill to control my diabetes." so the health benefits of a moderate exercise program is enormous even in the older population. olsen: they're very motivated. they're easier to work with, i think, in some respects because they've reached a point in their life where they know that things don't happen quickly all the time, and they're very disciplined, usually. the elements of becominphysicly f apply to al

a law there passed in 1985 after the name of the legislator. it offers a choice to unemployed workers. you can take a goal every week, an unemployment check the way we do in this country, or you have an option if you get at least nine other workers to make -- the unemployed workers like yourself to meet the following choice, you can get as a lump sum it can get your entire unemployment program of two years of checks in your hands right to the beginning -- you have to have nine other workers or more -- and have to use that money as the startup capital for a cooperative enterprise. the idea of the italian government was, if we give workers this to set up a job and enterprise, they will be much more committed to it than they would if they did not have that. >> how do they know they will do it? >> they don't. but they know the workers have an incentive. if they don't make that work, they cannot go back and collect unemployment the government does not spend much more than it would anyway, but it creates jobs and creates workers committed because it is their enterprise, to make that
